Salut,pe schema atasata ai niste puncte de test uitate pe schema si pe placa telefonului,poti sa incerci cu telefonul aprins sau prin introducerea incarcatorului in tel si masori exact asa:intre TP3100 si Tp3101 trebuie sa ai cam 13v asta e lumina de la display,si apoi intre Tp3105 si Tp3106 vezi daca ai tensiune acolo dac ai teniune acolo inseamna ca ai conectorul de pe placa defect,daca nu invertorul defect.
